The following pattern creates a race condition:
LOOP_DEV=$(sudo losetup -f)
...
sudo losetup "${LOOP_DEV}" "${ROOT_FS_IMG}"
If two steps similar to the above run in parallel, and both steps pick up
the same free loop device, they may try to mount different images with the
same loop device and one of the two stages will get a "device is busy" error.
To fix this, we should switch to the following pattern:
LOOP_DEV=$(sudo losetup --show -f "${ROOT_FS_IMG}")
This CL implements the above.`

TEST=Run buildbot run. Test case where we run out of loop devices and verify
logic still works.
